TMA-APACHE-4.1

Ensure Access to OS Root Directory Is Denied By Default

VisokaNivo 1Automatskaapache

Opis

The Apache Directory directive allows for directory specific configuration of access controls and many other features and options. One important usage is to create a default deny policy that does not allow access to operating system directories and files, except for those specifically allowed. This is done by denying access to the OS root directory. The <Directory /> block must contain a single "Require all denied" and no Allow/Deny (or the legacy Order deny,allow + Deny from all with no Allow/Require). Reads the main configuration (APACHE_CONF overrides; default /etc/apache2/apache2.conf, /etc/httpd/conf/httpd.conf or /usr/local/apache2/conf/httpd.conf) and every Include/IncludeOptional file.
